Bests & Worsts Reviews from Amazon

[Update after 2 months of use] Would not recommend this product. 1. Lock function even more spotty than original review. 2. Lock goes into blue "scanning" mode by itself without anyone/thing touching it. It has managed to unlock itself while I was inside the house (even with proper calibration). It has also deployed the deadbolt on its own with the door open or closing, which has caused damage the trim around the inside of the door (due to door closing with deadbolt deployed). 3. The app crashes for no apparent reason causing the lock to not operate. 4. The app signs out of the Kevo account for no apparent reason and you are given no notice until the lock is inoperable. 5. There have been times when the Kevo scans the phone, the phone acknowledges scan (vibrate and/or sound), then the deadbolt does nothing. This device needs some major overhauling. [Original review] I had higher expectations for this item. The unit looks great and is understated (a good thing). Installation is very simple and straightforward. Initial account setup is simple as well. The colored LEDs on the deadbolt are simple and informative. The major flaw is the unit's ability to read your phone and operate the lock. Initially, I skipped the calibration and the lock worked 9/10 times to lock or unlock the door. In order to have the lock properly identify whether the phone was inside or outside the home, I decided to calibrate the receiver. It took at least 10 tries to get a "successful" calibration yet the lock works intermittently at best now. It does not inspire the confidence that I can leave the house without a real key (go for a run, for example). Even with proper calibration and a 100% read of the phone, the lock has a few things you must live with: 1. The lock mechanism is rather loud when operating (think paper shredder for about a second). 2. It takes a few seconds for the lock to search for the "key" and operate the lock. 3. The Kevo app must be open (at least in background) on your phone for it to work despite being authorized to access Bluetooth at any time. In the end, it's a great concept, but the Kevo needs some refinement before I would truly recommend it.
